1. Math-7 NOTES Graphing an inequality: Open or Closed Circle??
DATE: ______/_______/_______
What: solving and graphing inequalities
Why: To solve one and graph one-step inequalities.
NAME:
Graphing an inequality:
Open or Closed Circle??
When graphing the answer to an inequality on a number line, we use an _________________________ circle for > or < signs, and a __________________________
circle for ≥ or ≤ signs.
How can you remember that? Here’s a little trick:
DOES THE BIRD GET THE WORM ?!?
If the bird “gets the worm,” his belly is full, so
we use a ____________________________ circle. If
the bird does NOT get the worm, his belly is
empty, so we use an _________________________
circle.
Graph the following inequalities on the given number lines:
x ≥ -4
2 < x
3) x ≤ 0
4) ≥ x

2. Solve AND graph the following inequalities (switch sign when needed):
-6x ≥ -12
9 – x < 13
24 ≤ x + 20
4) x > 5
- 2
5) < 4 x
6) x > -2 3
